Description

Phosphatidylcholines, Egg (CAS NO 97281-44-2) are a class of high-purity phospholipids primarily derived from egg yolk, serving as a critical source of choline and essential fatty acids. These compounds are vital for their role as natural emulsifiers and structural components of cell membranes, offering superior biocompatibility and functionality. They are essential raw materials for manufacturers in the pharmaceutical, nutraceutical, and advanced cosmetic industries seeking premium-grade ingredients for liposomal drug delivery systems, dietary supplements, and high-performance skincare formulations.

Application

• Pharmaceutical Excipients: Key component in the formulation of liposomes and lipid nanoparticles for targeted drug delivery and vaccine adjuvants.
• Nutraceuticals & Dietary Supplements: Used in brain health supplements, nootropic formulations, and liver support products as a source of bioavailable choline and phosphatidylcholine.
• Cosmetics & Personal Care: Acts as a high-performance emulsifier, penetration enhancer, and restorative agent in anti-aging creams, serums, and lipid-replenishing treatments.
• Research & Development: Essential reagent in biochemical research, cell culture media supplementation, and membrane biophysics studies.
• Food Technology: Employed as a natural emulsifier and stabilizer in certain functional food products and nutritional emulsions.
• Diagnostics: Used in the preparation of reagents and standards for clinical diagnostic assays.

Quality Control

Our Phosphatidylcholines, Egg are produced and tested under strict quality management systems. Each batch is analyzed to ensure it meets stringent specifications for purity, phospholipid content, and fatty acid profile. Certificates of Analysis (COA) detailing key parameters such as assay, peroxide value, and residual solvents are provided. We can supply grades suitable for applications requiring compliance with relevant sections of USP-NF, Ph. Eur., and cGMP guidelines for pharmaceutical excipients.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation. For long-term storage, keep frozen at -20°C or below. Allow the product to equilibrate to room temperature before opening to prevent condensation and moisture uptake.
